EATON CND Series Electronic Molded Case Circuit Breakers, NG Frame
Eaton CND Series electronic moulded case circuit breakers (MCCBs) are used in low-voltage electrical systems to protect against overloads and short circuits. These circuit breakers feature electronic trip units that provide protection and monitoring capabilities.
They have a moulded case construction, which provides durability and protection against mechanical damage.
These CND Series electronic moulded case circuit breakers have amperage ratings up to 1200A.
They feature three pole configuration for controlling multiple connections simultaneously.
These moulded case circuit breakers are equipped with electronic LSIG trip units to prevent a long time over current.
They further feature zone selective interlock communication to prevent unintended tripping of downstream breakers when upstream breaker trips.

Frequently Asked Questions
How does an electronic LSIG trip unit work in MCCBs?
The electronic LSIG trip unit continuously monitors the current flowing through the circuit breaker and trips the breaker if an overcurrent condition is detected.
The unit uses microprocessors and algorithms to accurately determine the current magnitude & duration and to provide selective coordination with other devices in the electrical system.
